1 Claim. (Cl. 68-1 98) In the dyeing of yarn and other threads of twisted fibers or filaments, it is a common practice to force the dye liquor through a mass of yarn while wound on a spool-like drum called a dye beam. One common type of beam consists of circular cast iron heads at the ends of a perforated cylindrical body or screen frequently made of stainless steel, the ends of the latter being telescoped over and supported on inwardly extending annular flanges or rings formed on the opposed inner faces of the heads. The latter are suitably fastened to each other and clamped on the ends of the screen. The supporting flanges project into the sheet metal screen about one-half of an inch so that the perforated area of the latter will extend close to the inner faces of the heads to permit of a uniform penetration of the dye liquor to the entire mass of yarn on the beam. The beam is filled with yarn on a warping machine, and in order to drive the beam, what is known as a warper drum presses against it. During that filling operation the ends of the sheet metal screen frequently become outwardly flared to such an extent that they do not properly fit or engage the flanges or rings on the heads. That results not only in the yarn being damaged but also in the formation of irregular or uneven passages between the screen and the heads so that the dye liquor is permitted to channel out in one particular place instead of being evenly distributed around the screen.

The principal object of the invention is to provide a connection between the screen and its heads which will overcome the above mentioned trouble experienced with dye beams now in use.

Another object of the invention is to provide a connection between the screen and its heads which will permit the dye liquor to be discharged into the mass of yarn on the beam very close to the heads so that the entire mass of yarn will be uniformly treated.

A further object is to provide a connection between the screen and its heads which will not only prevent the screen from being flared out at its ends and hence prevent channeling of the dye liquor but will also give the beam a much longer life.

Other objects and advantages will appear from the following detail description, taken in connection with the accompanying drawing, in which;

Figure 1 is a side elevation of the dye beam.

Fig. 2 is an enlarged detail side elevation of one end of the beam with part of the head and screen shown in section.

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail sectional view of parts shown in Fig. 3.

In the, preferred embodiment of the invention shown, the numeral I I. denotes the hollow foraminous cylindrical body of the beam which is preferably made of perforated sheet metal such .as stainless steel. The perforations l2 extend around and throughout the length of the body or screen except for narrow areas l3 at its ends. The open ends of the screen are closed by the usual circular cast iron heads M on the inner opposed faces of which are integral rings or annular flanges l5. The latter are concentric with the heads and telescope into the ends of the screen as shown in Figs. 2 and 4 so as to support the same. These flanges or ribs [5 extend into the screen beyond the approximately one-half inch side areas l3 and past at least the endmost circumferential row of perforations l2, so that the outer surfaces of the flanges have a sufficient area of contact with the inner surfaces of the ends of the screen to prevent the latter from being outwardly flared when the beam is in the working machine. When the perforated metal from which the barrel or body I I is made is one-eighth of an inch thick, the flanges l5 will extend into the screen about one and fivesixteenths of an inch. Since these wide flanges or rings will underlie one or more of the circumferential rows of perforations, they are formed with suitable passages which will permit the dye liquor to flow from the interior of the beam through the perforations opposite the flanges or vice versa when the flow is reversed. These fluid passages are in the form of closely spaced channels or grooves l6 formed in the outer peripheral surfaces of the flanges or rings and extending from their free edges to within about one-half of an inch of the planes of the inner surfaces of the heads M, as shown in Figs. 2 and 4. The channels l6 extend in a direction axially of the beam and are preferably of substantially semi-circular shape in cross section so that the outer faces of the rings are of fluted shape. Due to the circumferential spacing of the channels, the portions of the outer peripheral faces of the rings between the channels form annular rows of circumferentially spaced ribs which extend axially of the beam and are in supporting contact with the inner surfaces of the end portions of the cylinder. The channels are also of such size and so spaced that all or substantially all of the perforations l2 which are radially opposite the rings will communicate with the channels, and hence the dye liquor may reach the yarn next to the two heads.

3 It has been found in practice that the improved connection between the ends of the screen and the heads of the beam will efiectively prevent the outward flaring of the screen ends and hence prevent damage to the yarn and channeling of the dye liquor, and at the same time provide a beam which will last much longer than 7 those now in use.

What is claimed is:

A dyeing beam comprising a hollow cylinder with spaced perforations, the perforated area extending substantially to the ends of the cylinder, a pair of circular heads secured to the ends of the cylinder, the heads having fiat inner faces against which the ends of the cylinder are abutted, cylindrical rings formed concentrically on the inner faces of the heads and telescoped into the ends of the cylinder, the outer peripheral surfaces of said rings being formed with circumferentially spaced fluid-flow channels extending axially of the beam from the inner ends of'the rings to points slightly spaced from the flat inner faces of the heads, the portions of said outer peripheral surfaces of the rings between the spaced channels forming an annular row of circumferentially spaced ribs extending axially of the beams and arranged in supporting contact with the inner surfaces of the end portions of the cylinder, the width of said rings in a direction axially of the beam disposing said channels in communication with at least the endmost perforations of the cylinder to cause fluid passing through the last mentioned perforated to travel close to the fiat inner faces of the heads.
